Synthesis and in vitro Fungicidal Activity of a Series of Novel N‐(Heterocycly)phthalimides

Abstract A series of novel phthalimides was prepared and tested for antifungal activity in vitro against seven phytopathogenic fungi: Rhizoctonia solani , Fusarium oxysporum f.sp. cucumerinum Owen., Botrytis cinerea , Fulvia fulva , Sclerotinia sclerotiorum de Bary, Phytophthora capsici , Botryosphaeria berengeriama. The results showed that those compounds holding the structure of 6‐methylpyridin‐2‐yl exhibited good activity against Phytophthora capsici and Botrytis cinerea.
